Mammogram

Overview

Definition

This exam uses low-dose x-rays to make a picture of breast tissue. The picture is called a mammogram.

The United States Preventive Services Task Force (USPSTF) recommends that women aged 50-74 years old get a mammography every two years. Other organizations recommend screening every year starting at age 40. Women who are at high risk for breast cancer may need to have mammograms starting at an earlier age and more often. Most organizations in the United States and Canada recommend regular screening. There are some differences of opinion among these groups, such as when to start and how often to have the screenings. Talk to your doctor about what is best for you.

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. If you are planning to have a mammogram, your doctor will review potential problems with you.

A mammogram does use radiation. You and your doctor will weigh the harms and benefits of this test. A mammogram may not be advised if you are pregnant. Be sure to discuss these risks with your doctor before the test.

Results

The radiologist will look at the images and may speak with you at the end of the exam. You will usually receive your results within seven days. If you do not, call and ask for the results.

Your doctor will have a report and either send you a letter or talk to you about your condition. The next mammography is usually done in 1-2 years if everything is normal.

Mammograms can sometimes detect things that look like cancer, but are not. If something is noticed on the mammogram, you may need to have other tests done, like an ultrasound or a breast biopsy. This will help determine if there is an actual problem or if everything is fine.

Also, like all screening tests, the mammogram will not detect every single abnormality.
